devplist uboot

"devplist" in U-Boot is short for "device priority list". It is used to specify the order in which U-Boot should try to boot from different devices, such as flash memory, SD card, or network. The devplist can be configured through the "bootcmd" environment variable, which contains a sequence of commands to be executed during the boot process. By default, U-Boot tries to boot from the first device in the devplist. If it fails, it moves on to the next device in the list until a successful boot is achieved.
